Be it known that I, CLARENCE S. MUN'Ro, a citizen of. the United Statesresidiiig at Charleston, in the. county of Kanawlia and State of; West Virginia, have invented certain new and.usef ll-Improvements in. Regis tering Valves, of whichthe following is a SPWl Q L O I, referencebemg had therein to the accompanylng. drawings.

This; lnvention. relates to; a registering valve or a tire gauge? valve, and the ob ject ofthe inventionis the. production of a comparatively simple and efficient device, that comprisesa mmlmum. number of parts,

" and, which is durable; and efficient in operation.

With this. and other objects in view, my invention comprises certain novel; combinations, construct-ions and arrangements of parts as will be hereinafter described, illustrated in. the, accompanying. drawings, and more particularly pointed out in the appended claims. i

I the dr w ngs? 1 a Figure 1 is a vertical, central, sectional View of a device or structure, constructed in accordance with the present invention.

Figure 2 is a fragmentary view of the device, showing parts in elevation.

Figure 3 is a perspective view of one of the two collars of the device.

Figure 4 is a perspective view of the plug device.

Figure 5 is a perspective View of the absorbent washer.

Referring to the drawings by numerals, 1 designates the hollow stem which is externally screw-threaded throughout its entire length.

Threaded upon stem 1 is the nut 2 that receives the inner or lower end of the fragile casing 3; this casing 3 is preferably formed of glass and, consequently, to minimize the number of casings lost in construction, by reason of breaking the same, when the por tion 4 is formed over againstthe glass in any suitable manner, I provide a yieldable or rubber washer 5, interposing the same between the body of the nut 2 and the extreme inner end of the glass casing 3, so that there is a slight yielding action obtainable when the nut is fastened upon the casing 3, at 4. I have found from actual experience that without my yieldable washer 5 a large percentage of the glass casings are crushed it comes in contact with'the' shoulder weer VIRGINIA, a,

or broken in the assembling reason of my invention nut and'the fragile casing. sis accomplished with efficiency, greatly reducing'the number a of casings 3Lthat would otherwise be crushed for broken While assembling,

A, head .6 is threaded upon the inner or lower end of he stem 1, and thisheadis process, butby the a sis emblingpf the a aa se pr a Y provided' with a shoulder 7, so that the-stem 1 can be quickly threadedto its proper position upon the head," without any enacting measurements being required, since theinner end of stem'lwillbe properly seatedw-hen the head. (Fig. 1) with the clamping washer 9 pressing against saidptube, and plate 10 rests against clamping washer the inner tube tightly *qlampedagainst the head 6,.

Y .The' head; 6 is provided with a al s...

socket 12 in which is seatedthe plug device 1'3; the body of; shaped, and extending'froin' the'body is a tit 14, upon which tit-14 is placed one end of the rubber tubing 15. The end of rubber tubing 15 upon tit 14 is fastened thereon by suitable fastening means, such as wire, 16, Fig. 1. All that is necessary to fasten the plug device 13 in the socket 12 is to press over a part of the metal of which head 6 is formed, at 17;

v 9, with 1 1a. 11v screwed tightly 'agalnstj'plateld to hold i the plug device .is conical r it will'be seen that when i I the metal is pressed over at 17 by reason of the conical structure of socket 12, the plug device cannot .be forced too far into the head 6. 1 i i The gauge plunger 18 is placed in stem 1, with a cap 19 on its outer end. The gauge plunger showsthrough the'casing 3, to per-. mit the observer to readily read the indicating numerals on the plunger. The'inner end of the gauge plunger 18 is provided with atit- 20, which is exteriorilyconstructed similar to the tit 14. Upon tit 20 is placed the other end of the rubber tubing, andsuitable fastening means, such as wire 16 secures the tubing upon the tit 20. Two collars 21, of similar structure, are employed,

one being placed upon tit 14 and another.

being placed upon are provided with upon which the ends of coil spring 22 easily thread; these collars 21 serve as a fastening means for holding the ends of the coil spring tit 20, and these collars external, spiral grooves terior of the device, as the water has been found, under test, to be absorbed by the washer thereby preventing it from passing into the device and thus the efficiency of the device is greatly increased by reason of water, or other foreign substances, such as dust, not passing into the interior of the device.

While I have described the preferred embodiment of my invention, and have illustrated the same in the accompanying draw ings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What I claim is:

I 1. In a device of the class described, the combination with a stem, of a. head on said stem, a plug device provided with a tit in said head, a gauge plunger provided. with a tit in said stem, a rubber tubing on said tits, collars provided with spiral grooves on said tits, a packing of absorbent material on the tit of the gauge plunger between the collar carried thereby and the gauge plunger, and a spring threaded in the spiral grooves of said collars and having a portion surrounding the rubber tubing.

2. In adevice of the class described, the combination with a stem, of a head on said stem, a gauge plunger in said stem, absorbent means in said stem and engaging said gauge plunger, and means forming communication between the head and the gauge plunger.

In a device of the classdescribed, the combination with a stem, of a head on said stem, a gauge plunger in said stem and rovided. with depending means, an absor ent washer on said depending means, and means on said depending means and connected to said head forming a communication between the head and the gauge plunger.

4. In a device of the class described, the combination with a stem, of a head on said stem, a gauge plunger in said stem, said gauge plunger provided with a tit, an absorbent washer on said tit against the inner end of said gauge plunger, and means connected to said tit and also connected to the head forming a communication between the head and the gauge pltuiger.

In testimony whereof I hereunto afiix my signature.
